IgA肾病肾穿刺病理分级都是什么?目前,IgA肾病是一种比较常见的原发性肾小球疾病。了解其病理分级有助于认识疾病状态。今天我们就来介绍一下IgA肾病的肾穿刺病理分级。

Ⅰ型(轻微病变):肾小球仅有轻度系膜细胞增加;无节段硬化,无新月体,无肾小管和间质病变。

Ⅱ型[局灶节段肾小球硬化(FSGS)样病变]:肾小球呈现类似特发性FSGS样改变,伴肾小球系膜细胞轻度增生;无新月体,无肾小管和间质病变。

Ⅲ型(局灶增殖性肾小球病变).小于50%的肾小球细胞增生,细胞增生最初可仅限于系膜区,或可由于毛细血管内细胞增生致肾小球毛细血管袢阻塞。可见新月体。绝大多数Ⅲ型病变示肾小球节段细胞增生。无肾小管和间质病变。。

Ⅳ型(弥漫增殖性肾小球病变):大于或等于50%的肾小球细胞增殖,像Ⅲ型病变一样,细胞增生可是节段或球性的,可见新月体,无肾小管和间质病变。

V型(晚期慢性肾小球病变):40%以上肾小球球性硬化;可表现为上述各种肾小球病变;皮质小管大于40%的小管萎缩或小管数减少。

通常,从I型到V型,肾脏病变程度逐渐加重。

IgA肾病肾穿刺病理分级都是什么?看了上面的介绍,希望对大家了解IgA肾病有所帮助。同时,IgA肾病患者应及时就医,在专业医生指导下进行规范诊治,以利于病情管理。
